Tilt your phone and you will be able to tilt your glider forwards or in reverse once you launch the penguin. You can offer up range in exchange for doing some turns and other techniques if you tilt it back all the way or forward all the way and hold it there. These will make you coins and will enable you to complete numerous missions. Or, you can manage the direction of tilt without turning, if you wish to go a really high height rather of a far away. Both will make you bonus coins.
